lsvtec blueish smoke????help
just a few thoughts...
When you assembled the rings...The gaps in the rings do NOT line up correct? that means none of the rings even the three oil rings( I assume Honda uses three oil rings like most others do.)
next possibility... Did you bore your motor? When you put the rings inside the bore did you have to compress them to make them fit in the bore? It is a good practice to put each ring in the bore of its cyl to check the ring gap. If the gap is to big or to small it causes problems. It may be that yours is to big? Did the shop that did your cyls have the pistons? They should have sized the cyls to match each individual piston and then marked them so you would install them correctly. Or if they did the build so they could install them correctly.
Basically it all boils down to the fact that somehow you are getting oil in your cyls. from the rings is a possibility. The head gasket is another. So is the guides. Just because they are new does not mean they are sized right. Also there should be seals on the valves to prevent to much oil from getting on the valves.
Another possibility is a crack in the head. It would be unusual to have a crack into an oil passage but it is a possibility and more so if the head has been ported. Do your intake valves have oil on them? The exaust valves may have oil from the exaust but the intakes should be clean unless that is where the oil is getting into the cyls.
hope this helps as something to look for. All this is assuming that you do still have oil on your plugs like you did before. If you do have oil in the cyls then a compression test will not tell if your rings are sealing because the oil will seal them.
good luck

well I sized each individual ring to each individual cyl and piston. So that they go into them correctly. There is still oil on the plugs. The intake side of the valves is clean as a wistle where on the other hand the exhaust side is really gummed up with oil. I have oil leaking out between the exaust gasket!! The valve seals were vacuum tested before I put it all back together to insure that wasnt the problem. The weird part is that It seems like it is worse now. Partial throttle at low rpm doesnt smoke hardly at all, but full throttle at low rpm smokes alot. Higher rpm smokes no matter how hard I excel, but decel never smokes. I am thinking that the cyl walls are outta spec, but according to the machine shop they are fine. the cyl where honed both times and never bored. (even though I shouldof went oversized). and all of the ring gaps where set very far from each other.
well I did another compression check today and I had 275-280 across the board except for number4 which was165. I then took some oil and dumped it into number four and did another compression check and I almost broke the guage it shot up so high, atleast 50 more. This pretty much means that my rings arent seated right?
I have a very simular problem. Except my compression is 8.6:1 and all my cylinders check out at 150 each cylinder. I have a little bit of smoke when the car idles after a run and there is a loud ticking noise. The valves have been recently adjusted and the sound is still there. My mechanic's opinion is that it is extreme piston slap in a loose cylinder. It is possible that the hole was over honed and the piston is too loose in there. He sez its probably time to go .20 over on my motor. Hope your situation is diff. Hope this helps a little.
